Technical description

In the Linux kernel, the following vulnerability has been resolved:

nvme-tcp: fix possible use-after-free in transport error_recovery work

While nvme_tcp_submit_async_event_work is checking the ctrl and queue

state before preparing the AER command and scheduling io_work, in order

to fully prevent a race where this check is not reliable the error

recovery work must flush async_event_work before continuing to destroy

the admin queue after setting the ctrl state to RESETTING such that

there is no race .submit_async_event and the error recovery handler

itself changing the ctrl state.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
